chemical energy (from molecules such as saccharides, fats, proteins we eat) that is transformed into ATP (Adenosine Triphosphate) in cell respiration (glycolysis, Krebs' Cycle and Electron Transport Chain).
Whenever a pump at a cell membrane wants to get a substance in low concentration to an area of high concentration, it makes molecules of ATP bind to it, these ATP molecules split into ADP (AdenosineDIphosphate) + Pi and therefore release this very chemical energy that was stored in cell respiration. Eventually, it is this energy that also makes the pump work.

What is the difference between potential and active energy?
Potential energy is energy that has the potential to be active. For example, when you pick up a pen, that is gravitational potenial energy, becasue it has the potetial to be dropped, in grvaity. Active energy would be when the pen is droppped and it is moving, it is active. It has a source of energy. Active energy is energy that is moving and working.
Why might the amount of energy needed by two girls of the same age be different?
Because they may be more active than each other!
Why active transport is a energy dependent process?
It is because active transport requires energy for it to work.
Is kinetic energy a source of activation energy?
Kinetic energy is active energy.
Why is energy needed by the body?
Energy is needed to keep your body in action!
What type of energy does active transport require?
Yes, energy is needed for active transport, while energy is not needed to be inputted for passive forms of transport.
The energy needed for active transport is usually supplied by what?
The energy needed for active transport is usually supplied by Mitochondria and ATP.
What is needed to facilitate active absorption?
a protein carrier and energy
Do facilitated diffusion require energy?
No energy is needed because it's a part of passive transport, not active transport.
Why do cardiac muscle cells have a large number of mitochondria?
Cardiac cells are very active. A lot of energy is needed
Active transport always requires?
For active transport to occur, energy is needed in the form of ATP. During respiration energy is released in the form of ATPThe reason why energy (ATP) is needed with active transport is because active transport is movement of molecules from a low concentration to a high concentration so its going againstthe concentration gradient. As its going against the concentration, energy (in the form of ATP) is necessary or else this process will not occur.
How does oxygen make you more active?
Oxgyen is needed for aerobic respiration, which gives out energy.
What requires vesicles for transportation across cell membrane?
It is a type of active transportation.So energy is needed.
Describe the two methods of active transport?
The 2 methods of active transport are taking the energy and using the energy to where the cell is doing the work,the cell will transport what is needed and all us done.
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
What is the difference between potential and active energy?
Potential energy is energy that has the potential to be active. For example, when you pick up a pen, that is gravitational potenial energy, becasue it has the potetial to be dropped, in grvaity. Active energy would be when the pen is droppped and it is moving, it is active. It has a source of energy. Active energy is energy that is moving and working.
How is passive transport different then active transport?
An example of passive transport would be the process of osmosis (water diffusing between a membrane-- from an area of high concentration to an area of low concentration). It is known as passive transport because no energy is needed in order to move the water across the membrane. When no energy is needed to move the substance it is considered passive transport. On the other hand, when energy IS needed to transport molecules or substances across a membrane it is referred to as active transport. An example of this would be a calcium pump located in the lipid bilayer of a plasma membrane which can transport potassium (K+) ions across it. Energy is needed in order to move those potassium ions across the membrane, and therefore is referred to as active transport.
